So I have droped the feul tank to get all of the old gas out after the car sat for 12 years and I am wondering if you all would change the sending unit even though it was working fine. Also I do not need the vapor line since the car will have a 350 carbed with no emitions. What would you guys do? And if I should change it what would be a good one to get for a simple 350 with no emitions ?

Thanks

I recently had the tank out of an 88 GTA in order to change the fuel pump, and I was really torn about what to do with the sending unit. It worked fine before removal, so I gambled and put the old sending unit back in. All good so far, and I don't anticipate any issues in the future.

The old sending units are much more robust (better quality) than their modern replacements. The new styles have a printed circuit rather than a a wirewound resistor and fail much more frequently.

The only other reason I would remove a 25 year old unit would be to get an 18 year old brunette unit in exchange.

If the original is for a carb setup and it's not rusted, just clean it up real good. Rod the tube out in case it's got crusties built up in it, which it almost certainly does, from sitting around. Get a new "sock" filter.

Keep the return thing installed and operating. It's definitely worthwhile. It'll save you from problems you don't know about yet, that you will almost surely have otherwise. "Emissions" (correct spelling) isn't the issue.
